REVIEW:
Probability is the # of desired outcomes/total possible outcomes
1. Basic Probability
Find P (rolling a 5) =
2. Mutually Exclusive Probability (OR)
A spinner has 5 equal sectors of red, blue, yellow, green and orange.
Find P (red or green) =
3. Non-mutually Exclusive Probability (OR with overlap)
Given a set of numbers: {-2, 0, 1, 4, 7, 10}
Find P (even or negative) =
4. Independent Events (with replacement)
Find P (heads AND heads) =
5. Dependent Events (without replacement)
You are given a bag of 10 jolly ranchers with 5 blue, 3 red, and 2 green.
Find P (blue AND blue) =
